Episcleritis

A localized patch of inflammation affecting the outermost layers of the sclera (white of the eye) immediately underneath the conjunctiva. The condition usually occurs for no known reason, mainly affecting middle-aged men. In some cases, it is a complication of rheumatoid arthritis. The inflammation may cause a dull, aching pain and there may be photophobia. The disorder usually disappears by itself in a week or so but may recur. Symptoms may be relieved by using eye-drops or ointment containing a corticosteroid drug.
